Sky High Danger : Ash Grove House Press : 9780999645314 : 0999645315 : 07 Dec 2017 : Summer isn't looking good for thirteen-year-old Tyler. His dad has moved to Singapore and his mom has left for Las Vegas to marry her new boyfriend. That leaves Tyler stuck in El Paso with his aunt and uncle. On the plus side, his cousin Mackenzie is pretty cool and Mac's uncle Eric is a pilot. Things get intense when Eric goes missing and Tyler and Mac have to find him. But rescuing Eric means Tyler and Mac will have to risk everything. Maybe an El Paso summer won't be so boring after all.
